A bizarre foam blob is taking over a street in California — here's what's causing it

A mysterious giant foam blob is filling up a street in Santa
Clara, California. KTVU Fox 2 is on the scene.

The blob was for a time a mystery, with law enforcement unable to
explain it. But the Santa Clara Fire Department has Tweeted an
explanation: a malfunctioning fire suppressant system. Workers on
the scene have been seen stacking sandbags.

We are aware of the FOAM incident from Fire Suppression system that malfunctioned. @SJFD notified. Santa Clara Agencies providing support.
